After a quick look at MC44BS373 the I2C bus runs 0-800K. Have a look at the Software I2C routines to see http://www.freescale.com/files/microcontrollers/doc/app_note/AN1820.pdf  depending on how fast you run the I2C clock you can get away with software I2C.

The you will need 6 pins for your LCD display. I would suggest looking at the hc908qy devices. You can get away with using an hc908qt device but then you need a shift register to interface your LCD and the cost difference and software overhead is not worth it.
